In this first part of the value analysis series, I will cover Total Cost of Ownership (TCO) and why do you need it?.
TCO is an assessment of total cost for a product (hardware/software or even a car) over a the life time of the product.The total cost includes upfront purchase cost + any (hidden) ongoing costs (monthly, yearly) such as maintenance, operational, licensing etc.Understanding the total cost over the lifetime of the product will help you asses the over all value to the business and make apple to apple to comparison to other alternatives much easier.There is a simple exciting formula for calculating TCO.
Are you ready?
TCO = One Time Costs + Recurring Costs x Expected Duration
One Time Costs: Hardware/software purchase cost, shipping, installation, professional services, decommissioning etc.
Recurring Costs: Maintenance, upgrades, annual license fees, support
Expected Duration: The expected life time of the product/service
Let me illustrate with an example (see scenario table below):
Company XYZ Corp is evaluating upgrading their current SAN or leasing a new one. They have asked you to calculate both TCO options and make a recommendation.
Costs of Hardware Maintenance: $30,000/year
Costs Software maintenance: $20,000/year
Costs of Storage: $10,000/year
TCO = $30,000 + $20,000 + $10,000 x 5 years = $300,000
$300,000 is the total cost of onwership over the 5 years life time of the upgraded storage array.
Now let us take a look at Option 2
Costs of lease of new storage array: $50,000/year
Costs of installation of new storage array: $20,000
TCO = ($50,000 x 5 years) + $20,000 = $270,000
TCO for option 2 is lower than option 1. Therefore, you should recommend that XYZ Corp select option 2 as it presents a better TCO.
This was a simplified example to illustrate how to calculate TCO. I hope this helps.
Thank you for reading.
